pg_statsinfo

More useful statistics information for DBAs

NTT has developed "pg_statsinfo", that collects database activities and statistics
automatically, and shows the information to DBAs in user-friendly shapes.
Also pg_statsinfo can collect statistics from multiple DBs, so this tool makes
it much easier to monitor the status of many DB servers

PostgreSQL provides many useful statistics about DB activities and conditions via
system views and contrib modules. But for many DBAs, it is difficult to see whether
a DB has problems or not from original statistics information.
